Definitions

  • the present invention relates to a printer having two or more interfaces, and more particularly to a printer connected to an external host device having a plurality of peripheral devices.
  • POS point of sale
  • a POS system usually includes one host device, and a plurality of peripheral devices connected thereto, such as a printer, a bar-code reader and a magnetic card reader.
  • FIG. 6 is a block diagram showing one example of conventional POS systems.
  • One of a variety of commercially available personal computers is often used as a host device H in order to save cost.
  • the personal computer usually has one or two serial ports, and one parallel port.
  • a maximum of three peripheral devices i. e. devices Q 1 and Q 2 and a printer P, may be connected to the host device H.
  • the host device H lacks a connection port for connecting a fourth peripheral device Q 3 or more peripheral devices.
  • an expansion board For connecting more peripheral devices than the number of ports of the host device H, an expansion board must be added to the host devices H to provide an increased number of ports.
  • a complex control program is required for controlling the expansion board. This results in an increase in the cost and an extended period for development of the entire POS system.
  • a scanner/printer connectable to a computer in which an optical scanner and a printer are integrated to provide a fax function and a copying mechanism.
  • this is a stand-alone type with a particular scanner mounted in a printer, and has no expandability for connecting other peripheral devices.
  • Japanese Unexamined Patent Publication JP-A8-123640 (1996) describes a connection switch mechanism provided between a host device having only one interface and a plurality of printing devices, for distributing signals by switch circuits on signal lines.
  • This mechanism requires a complicated and costly switching circuit for switching a data bus and a control bus having a plurality of signal lines.
  • the mechanism is applicable only to parallel communication based on a busy signal.
  • An object of the present invention is to provide a printer for enabling connection of a larger number of devices than the number of connection ports of an external host device.
  • the invention provides a printer comprising:
  • a printing station for printing a recording medium based on print data supplied by the external host device
  • a signal processing circuit for performing an output through operation to transmit data received from the external host device via the first interface, to the peripheral device via the second interface, and an input through operation to transmit data received from the peripheral device via the second interface, to the external host device via the first interface.
  • data received from the external host device may be transmitted to the peripheral device in the output through operation.
  • Data received from the peripheral device may be transmitted to the external host device in the input through operation.
  • data communication between the external host device and peripheral device, and data communication between the external host device and printer may be effected via the first interface. Only one interface connection port is adequate for the external host device. It is therefore possible to connect a larger number of peripheral devices(including a printer) than the number of connection ports of the external host device.
  • a first protocol of the first interface and a second protocol of the second interface are different from each other.
  • the first protocol is converted to the second protocol for the output through operation and the second protocol is converted to the first protocol for the input through operation.
  • data communication may be effected between the external host device and peripheral device even where the protocol with the external host device and the protocol with the peripheral device are different from each other.
  • a protocol means a condition for uniquely defining a command system, communicating conditions (communication rate, data length, parity and so on), type of interface (serial communication, parallel communication, Ethernet or the like), and a communications protocol (DTR mode, Xon/Xoff mode, STX-ETX mode, network protocol or the like).
  • the external host device may be operable on only one protocol in realizing data communication with a plurality of devices (including the printer) having varied protocols. This reduces the load of the external host device. Moreover, data communication can be made with peripheral devices having protocols with which the external host device cannot cope, resulting in high expandability of peripheral interfaces.
  • the first protocol and the second protocol conform to a serial interface standard.
  • the protocol conversion between the external host device and various peripheral devices becomes more effective since a serial interface standard requires setting of various conditions such as number of signal lines, synchronous or asynchronous, baud rate, data length, with or without a parity bit, odd number parity or even number parity, stop bit length, flow control method and so on.
  • FIG. 1 is a block diagram showing one example of connection between a printer according to the invention and an external host;
  • FIG. 2 is a block diagram showing an electrical construction of the printer P according to the invention.

  • the interfaces 21 and 22 also have connectors for serial interfaces such as RS-232C, and are connected to the external host H and peripheral device Q through signal cables L 1 and L 2 , respectively.
  • the CPU 10 is disposed between the interfaces 21 and 22 , and has operating modes including a print mode, an output through mode and an input through mode.

  • the CPU 10 receives data transmitted from the external host H via the interface 21 , and transmits the data to the peripheral device Q via the interface 22 .
  • the CPU 10 receives data transmitted from the peripheral device Q via the interface 22 , and transmits the data to the external host H via the interface 21 .
  • the external host H can exchange data with the printer P and peripheral device Q through the interface 21 . It is adequate for the external host H to have only one interface connection port.
  • the external host H can be connected with the devices (including the printer) greater in number than the connection port of the external host H.
  • the construction shown in FIG. 1 exemplifies the interface 21 connected to the host H and the interface 22 connected to the peripheral device Q both conforming to a serial interface standard. It is also possible a) that the interface 21 is based on a serial interface standard while the interface 22 is based on a parallel interface standard, b) that the interface 21 is based on a parallel interface standard while the interface 22 is based on a serial interface standard, and c) that both interfaces 21 and 21 are based on a parallel interface standard. Further, one or both of the interfaces 21 and 22 may be based on various protocols such as Ethernet. Where the interfaces 21 and 22 differ in protocol, the printer P has a function to convert the protocols, thereby to increase expandability of the interfaces.

  • DIPSW dip switches
  • nonvolatile ROM read-only memory
  • RAM random-access memory
  • the interfaces 21 and 22 conform to a predetermined interface standard such as for serial interfaces or parallel interfaces, and are connected to the external host H and peripheral device Q through signal cables L 1 and L 2 , respectively.
  • the station S 1 is connected to CPU 10 through an input/output circuit (I/O) 11 , and includes a receipt printer mechanism or a slip printer mechanism.
  • I/O input/output circuit
  • the RAM 40 has a receiving buffer 41 for storing data received from the interfaces 21 and 22 , a transmitting buffer 42 for storing data to be transmitted to the interfaces 21 and 22 , and a work area 43 for the CPU 10 to process signals therein.

  • the mechanism of station S 1 is caused to carry out an initial operation.
  • the CPU 10 reads values set by the dip switches 31 .
  • the dip switches 31 and 32 include a plurality of switches for setting various conditions. These conditions include whether the interfaces 21 and 22 are for serial communication or parallel communication.
